Is the amount of DNA in a human sperm cell the same as the amount of DNA in a human egg cell? explain.?

Answer 1

Yes, as they both contain only one copy of each chromosome.

The sperm cells might be X or Y sperm cells, with the X cell containing marginally more DNA, whereas the egg cell is always X. This is because of the sex chromosomes, XX in females and XY in males. In fact, sperm cells can be seperated based on their weight, into X and Y cells.

The poster above is mostly right except that the chromosomes aren't single stranded.

It is worrying that the poster above believes there to be single stranded DNA in sex cells and is also a biology teacher!

If it were true, this biology teacher should be well aware, that single stranded DNA cannot associate with histones and thus cannot form the nucleosome. This would result in unstructured chromosomes which would form a big gooey mess!

Answer 2

The amount of DNA in an egg cell is actually slightly more then a sperm cell. While all the above answers are correct in stating that each carries 23 chromosomes, they have forgotten that the egg also contributes a small amount of mitochondrial DNA, therefore the egg contributes a tiny bit more!

Answer 3

a million/2. Chromosomes are made up of DNA, and there are two times as many Chromosomes in a physique cellular then there are in a sperm cellular. Chromosomes have 2 complete gadgets, are termed Diploid, and the actual huge form is 40 six. Sperm has one set (meant to later integrate with the only set that an egg could have besides), are termed Haploid, and the actual huge form is 23

Answer 4

both human eggs and sperms have 22 non-sex related chromosomes and 1 sex-related chromosome (called X or Y).
The egg must have an X chromosome always, while a sperm can either has X or Y (females are XX while males are XY)
since a Y chromosome has less DNA than an X chromosome, a sperm with Y chromosome has less DNA than an egg, while a sperm with X chromosome has the same amount of DNA as an egg.

Answer 5

Yes, each has 23 single-stranded chromosomes - one from each homologous pair.

Technically, a sperm with an X-chromosome has more DNA than a sperm with a Y-chromosome because X is quite a bit longer, but your question doesn't say anything about that. Half of the sperms will have X; half will have Y.


Yes, the chromosomes are single-stranded in eggs and sperms. These cells are gametes which are formed by meiosis. Meiosis I splits the homologous pairs of chromosomes from each other, forming two sets of double-stranded chromosomes, 23 double-stranded chromosomes in each set in humans. Meiosis II splits the double strands apart from each other, forming sets of single-stranded chromosomes.

Answer 6

Yes, both have one half of the chromosomes (made of DNA) in that our species has in its normal cells. When combined (fertilization) they form a zygote- the first body cell of a new organisms, and there DNA unite to once again create a complete full compliment of DNA

Answer 7

Both the spermatozoon and the oocyte have the haploid number of chromosomes which is 23 and each of the chromosomes in normal individuals contain equal amount of DNA.

Answer 8

If you refer to the chromosomes yes, both human sex cells (gametes) have 23 cells whose during fermentation form the 46 chromosomes zygote that will later became a fetus.
